Just purchased
Charged up , registered,  balanced phone , opened mimo app , paired phone to osmo 3 .
Ok after this my phone displayed image and then description bubbles explaining all tabs , when this finished a custom menu pops up 3 tick boxes
        Diagonal and square lines
        M button setup
        Cant think off third
Now immediately this pops up i can check boxs but cant do anything else . Progress is stuck

You should post and read in the mobile 3 forum here - you're in the Pocket forum, different device.  Anyway, first check that in your phone's settings you have text sie set to normal.  That's usually the fix for this problem.
